PORTABLE ELIisHING DEVICE.

` l Application filed July 19,

l To all whom t may concer/n:

Be it known that we, WILFRED EMPEY DENsMoRE LEWIS, JAMES S. ADAMsoN, and MARTIN JAMES MAHON, subjects of the King of Great Britain, residents of the city of Ottawa, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Portable Flushing Devices, of which the following is a specification.

This invention relates to improvements in portable flushing devices and the objects of the invention are to render the device capable of being readily transferred from one place to another and utilized to effect the cleaning out of trapsA of fixtures, to permit` of `the iushing device being readily attached to water taps of different diameters, so that the pressure in a water main may be directly exerted on any blockage' in the trap to force the said blockage out.

OFurthenf objects are to render the closing member of the flushing device capable of being inverted so that it'can be adapted to fit either a fiat waste generally found in kitchen sinks, or recessed wastes usually found on A Wash hand basins and baths, to adapt the closing member when utilized with recessed wastes to cover the air vent so that the water pressure from the tap will be directly applied to the blockage and the water will not escape through the back overflow.

Further objects are to rovide a water tight joint between the closing member and the waste and to secure the said closing member in the desired position, and generally to adapt the several parts to better perform the functions required of them.

With the above and other objects in view, the invention consists-essentially of the improved construction articularly described and'set forth in the ollowing specification and accompanying drawings forming part "of the same.

'In the drawings:

Figure 1 is a side elevation of the imj proved flushing device.

Fig. 2 is an enlarged sectional elevation of the improved flushing device, part of the tube being in elevation and broken` away.

Fig. n3 is an enlarged fragmentary sec- 4 tional elevation of the lower end of the tube.

the improved flushing" device comprising a closing member 10 which is formed like a frustum of a circular cone and is provided4 at the smaller end with a conical projection 11 of smaller diameter thanthe bodyy -portion of the closing member.

The upper portion of the closing member 11 is tapered while the lower face of the closing member 10 has an annular recess 14.` adaptedto receive a gasket 15 which is designed to form a water pipe joint between the closing member and the fixture on which the flushing device is being used.

A pipe 16 extends through the orifice 13 and is provided at the lower end with a pivoted hook 17 which engages with the grid portion of the waste and so holds vthe closing member in position, the said hook being actuated by the wire 18.

To facilitate pressing the closing member 1() over the waste of the fixture a wing nut 19 isthreaded on the pipe 16, and on rotation of the wing nut the said pipe is moved longitudinally to the closing member and causes the hook to engage the grid and so pull the closing member into position to form a water tight joint between the closing member and the xture.

A water tight joint should be obtained between the plpe 16 and the closing member 10 and to this end We provide a washer 20 of leather or other suitable material, which will be located between the wing nut 19 'and the closing member, so that when the wing nut is tightened it will press the washer against the pipe 16 and so make a tight joint. j

The outer end of the pipe 16 is threaded to a coupling 12 which is provided with a stepped tapered stem 22 adapted to fit into the fiexible tubular member 23, which is held in position on the :stem by the resilient clamping member 2.4 closed by means of a screw 25. l

On the upper endofthe flexible tubular member 23 a sleeve 26 is mounted which projects beyondthe end of the tubular member" and this projecting end of the sleeve is adapted to fit around a cap.

As taps vary in diameter it is advisable that provision should be made for the sleeve 26 to fit ordinary sizes of taps at present in use, and to facilitate bringing about this result we provided filing washers 29 which may be fitted around small taps, so that the tap with the washers willjust fit within the sleeve 26 which is then tightened in posi-` tion by the resilient clamp 27 closed by the screwy 28.

When the device is in use the closing member is secured in position above the waste of the fixture in which the blockage occurs and the sleeve 26 is attached to a tap. The hook 17 is engaged with the grid of the waste and the wing nut 19 is tightened thereby moving the pipe 16 longitudinally and .or cold water tap.

When a recessed Waste is encountered the closing member 10 will be reversed on the pipe 16 so that the end 11 will enter the recessed waste, and if an air vent or overiow extends from the waste then the lateral wall of the conical portion 11 will close the air vent.

The closing member is held in position as previously described and the pressure from the water main isv brought to bear upon the vblockage in the trap as described above to forcibly remove the blockage.

The closing member 10 may also be utilized on water closets and the conical formation of the body portion 10 allows it to fit in the fixture adjacent to the trap thereof, and the pipe 16 is now passed through the closing member 10 from the opposite directions to that shown in the drawings.

/ The closing member 10 will be held in position by any suitable means under such conditions, and the sleeve 26 will be attached to a water tap, so that the full force of water from a water main maybe utilized to flush out the fixture.

The pressure obtained with the ordinary water system is sufficiently great to remove any ordinary obstruction from a trap in the course of a few seconds, and by using hot .water` the trap is effectively cleaned out and any soap or other material adhering to the walls of the trap is swept away.

mamas Byl the use of this flushing device the water pressure can be directly applied to the blockage, and there is no necessity to disassemble a trap to remove the blockage therefrom, so that there is no dirt created when flushing the trap in this manner.

Moreover the saving of time in using this flushing apparatus and the fact that it does not. require skilled labor to attach the same, permits of its being used in household by women.

As many changes could be made in the above construction and many apparently widely different embodiments of our invention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matters contained in the accompanying speciiication andv drawings shall be interpreted as illustrative and not in a limiting sense.

`What we claim as our invention is:

1. A flushing device comprising a closing member, a pipe longitudinally mounted with freedom to be adjusted longitudinally in the closing member, a projection extending from the end of the pipe, al pivoted hook pivotally mounted on the projection, an operative wire for the hook extending longitudinally through the pipe,and means for connecting the outer end of the pipe to a tap.

2. A flushing device comprising a closing member, a pipe longitudinally mounted with freedom to, be adjusted longitudinally in the closing member, a projection extending from the end of the pipe, a pivoted hook pivotally mounted onr the projection, an operative wire for the hook extending longitudinally through the pipe, and means for connecting the outer end'I of the pipe to a tap, the second last mentioned means including a stepped tapered stem, a coupling connecting the stem with the pipe, a iexible tubular member connected to the coupling at one end and having its opposite end adapted to be connected to a tap.

.In witness whereof we havehereunto set our hands.
